利用2012年3月-2013年2月在鄱阳湖通江水道进行的定置网渔获物调查的数据，运用软件FiSAT II对翘嘴鲌(Culter alburnus)的生长参数以及种群补充模式进行了估算。结果显示，鄱阳湖通江水道翘嘴鲌体长范围为93-645 mm；体长(L, mm)和体重(W, g)的关系式为W =0.9×10-5L3.029(R2=0.975,n =317)，von Bertalanffy生长方程的各参数：渐近体长L∞=677.25 mm，生长系数K=0.140，理论生长起点年龄t0=-0.854。总死亡系数Z=1.514/a，自然死亡系数M=0.173/a，捕捞死亡系数F=1.341/a。鄱阳湖通江水道翘嘴鲌开发率E=0.886，资源处于过度利用状态。种群补充模式表明，鄱阳湖通江水道翘嘴鲌种群补充期在4–8月。因此，建议适当延长鄱阳湖的禁渔期，以利于其资源的恢复与保护。

In the present study, monthly carapace length frequency data ofCulter alburnuswere collected from the set net fishery survey in the waterway connecting the Poyang Lake and the Yangtze River from March 2012 to February 2013. ELEFAN? and Shepherd’s methods in the software package FiSAT II were used to analyze the growth, mortality rates and recruitment pattern of an unexploited population ofC. alburnus. The results showed that the length ofC. alburnus population ranged from 93 to 645 mm, and that the relationship between body length (L, mm) and body weight (W, g) can be expressed asW=0.9×10-5L3.029(R2=0.975,n=317). The estimated parameter for von Bertalanffy growth equation wasL∞=677.25 mm,K= 0.140, andt0=?0.854. Total mortality (Z) was 1.514/a, natural mortality (M) was 0.173/a, and fishing mortality (F) was 1.341/a. The exploitation rate ofC. alburnus was 0.886, suggesting resources ofC. alburnus were on the state of overexploitation in the study area. The recruitment pattern with less efficiency from April to August suggested that fishing ban period should be adjusted in order to restore and conserve the populations ofC. alburnus.
